[Haskell-beginners] http-conduit: Changelogs/notes on API changes

Hi, I'm trying to update the couchdb-conduit package to use the latest (stackage) version of it's dependencies. Is there any changelog, release notes, or even a blogpost which summarise how the API was changed between different major versions? And in general, is there a common practice for hackage packages on how are API-breaking changes are communicated? Cheers -- Minden jót, Sevcsik András
